The reason I'm curious is because using your car analogy, if I was a barely competent mechanic then management would probably be fine letting me perform oil changes, but when a classic Rolls Royce comes in with all original parts, management isn't going to let me touch that, right? They'll need to call in the big guns, whose rates are definitely higher than my "oil change" rate. I know that doesn't directly map with how medical procedures play out. I guess my real question is when and how does that balance out?
